I dropped my daily driver sedan with 2008 350z NISMO tuned suspension (springs, shocks, struts and sways.) Even though I was expecting more, I got a drop of around 1.6 inches all around. Everything felt excellent while driving in straight line or regular curves, no bouncing, firm ride, minimum body roll, all this on stock 17”x7 wheels with 225/50R17. When I took the first ramp to take the highway at the regular speed I usually take them (45-50 mph) I felt the front tire rub-bounce inside of the wheel well. I thought that something snapped, but when I checked all seem to be OK. The same event occur when taking a ramp turning right or left on the opposite side of the car. The mechanic that installed the suspension told me that it was only a matter of alignment and that everything will be fine after it.
Today, after 5 days, I did the alignment and switch the wheels for coupe 19” that came with 225/35R19. Although the diameter of the setup is even smaller than stock I still have the same issue. This is the alignment specs:

FRONTS: (Left Right)
Camber: -0.6 -0.7
Caster: 8.1 8.3
Toe: 0.03 0.05
SAI: 4.7 4.1
Cross Camber: 0.2
Cross Caster -0.1
Total Toe: 0.08

REAR: (Left Right)
Camber: -1.2 -1.1
Toe: 0.09 0.09

Any ideas what is causing the rubbing inside of the wheel well?

 

No opinions at all?

 

Just a caster issue.
